<P>PROBLEM TO BE SOLVED: To provide a pyrolytic equipment in which operation cost is reduced and the corrosion of a duct where a heating gas flows is inhibited. <P>SOLUTION: A first heating gas supplying means 103 for starting the operation, and a second heating gas supplying means 104 for operation after the start of the operation are mounted to form a heat gas supplying part to a pyrolytic drum 12, the second heating gas supplying means 104 is provided with a thermally-decomposed gas combustor 110 for combusting a predetermined amount of thermally-decomposed gas in the thermally-decomposed gas from the pyrolytic drum 12, a gas mixing part 111 is mounted for mixing a gas discharged from a heating gas discharging part 30 and recovered at a gas recovering passage 105 side, with a combustion waste gas from the thermally- decomposed gas combustor 110 to produce the heating gas, the gas recovering passage 105 is provided with a gas neutralization processing device and a dust collector 114, and further a gas cooling means 123 is mounted at an upstream side with respect to the gas neutralization processing device and the dust collector 114, for cooling the gas of the gas recovering passage 105. <P>COPYRIGHT: (C)2004,JPO |
